British bookie refunds all Olympic flame bets as perfectly kept surprise eludes all gamblers

LONDON - The perfectly kept surprise about who would light the Olympic cauldron caught out even the savvy British bookmakers.

So much so, that a leading oddsmaker is refunding all wagers because it was too tough for gamblers to guess the identity of the seven young athletes who had the honour Friday.

William Hill spokesman Rupert Adams says "the result was all but impossible to predict."

Adams says the betting operator is giving back "a five-figure sum" wagered by its clients.

Five-time rowing gold medallist Steve Redgrave was the longtime favourite. His role was carrying the torch into the Olympic Stadium to hand it to the seven young people.

There was also a late surge of wagers on former mile world record-holder Roger Bannister.
